1. A device for hot air jet dewaxing and reclaiming wax composition from a pattern for investment casting shell making, the device comprising:
a hot air supply mechanism;
a hot air jet dewaxing mechanism;
a liquid wax collection mechanism;
a liquid wax reclaiming mechanism; and
a bearing platform,
wherein an investment casting shell is fixedly installed on the bearing platform, a hot air outlet end of the hot air supply mechanism being in fluid communication with a hot air inlet end of the hot air jet dewaxing mechanism, a hot air outlet end of the hot air jet dewaxing mechanism extending into a cavity of the investment casting shell and facing a wax mold;
wherein the hot air has a temperature within a range of 120 to 170° C.;
wherein liquid wax generated in the cavity of the investment casting shell is configured to flow into a liquid wax inlet end of the liquid wax collection mechanism under gravity, and
wherein a liquid wax outlet end of the liquid wax collection mechanism is in fluid communication with a liquid wax inlet end of the liquid wax reclaiming mechanism.
